TAHITIAN LIME(Persian
TAHITIAN LIME (Persian Lime) Limes have many uses, including jams, jellies, marmalade and garnishing fish and other main dishes. The fruit is sold commercially as fresh fruit and also for processing although the Tahitian lime is preferred as fresh fruit because it is considered unsuitable for lime cordial products. The name “Tahitian” was given to the lime when the fruit was introduced from Tahiti to California. However, with the introduction of this variety into Australia in 1824 (possibly from Brazil) the fruit was then more commonly called the Persian lime. DESCRIPTION Large sized lime, generally 5 - 7 cm long and 4 - 6 cm in diameter. Colour of the fruit is green and pale lemon/yellow at maturity. The fruit has a distinct lime flavour and a moderate to high acidic level. The flesh at maturity is green and pulpy. Sold mainly as fresh fruit, Tahitian limes rarely have seeds and are excellent for growing in many areas of Australia. PRODUCTION OF LIME TREES Main crop harvest will vary with seasonal conditions and districts. January to March on the far North Coast areas. February to March on the Central Coast. April to July in cooler districts. The trees have little thorns and are moderately vigorous, growing from 2 to 4 metres high. Size depends on soil and rootstocks. Lime trees have the highest heat requirements of all citrus fruits and therefore grown in tropical or sub-tropical areas where better fruit quality is obtained. The trees grow continuously and are sensitive to cold. The Tahitian lime is slightly more cold resistant than other varieties, however frosts can damage both foliage and fruit. -

Printed in Brazil Reaction of tangerines genotypes to Elsinoe fawcettii under natural infection conditions Marcelo Claro de Souza1*, Eduardo Sanches Stuchi2 and Antonio de Goes3 Received 11 February 2010 Accepted 30 September 2010 ABSTRACT - A citrus scab disease, caused by Elsinoe fawcettii, is currently found in all citrus areas throughout Brazil. That being, given the importance of this casual agent, the behavior of tangerines and hybrids influenced by this pathogen was evaluated under natural infection conditions. This study was performed with plants around 15 years old without irrigation; 100 fruits of three plants were collected during harvest season, using a grade scale varying from 0 (absence of symptoms) to 6 (severe symptoms) the level of disease severity was determined. Among the cultivars, citrus scab resistance was observed in Citrus deliciosa, C. tangerina, C. nobilis; a mandarin hybrid (C. nobilis x C. deliciosa) and a satsuma hybrid (C. unshiu x C. sinensis). Among the other genotypes, symptoms were observed with levels of severity ranging from 1 to 3, indicating moderate resistance. Key words: Citrus scab, citrus crop, resistant varieties. INTRODUCTION In Brazil, E. fawcettii is responsible for citrus scab.

It was prepared as part of the Bureau of Land Management's Cultural Resource Manage- ment Program and is the second complete history of a BLM district in Colorado. A major objective of the Bureau of Land Management, Department of the Interior, is the identification, evaluation and protection of the nation's historic heritage and values, particularly those under the management of the Bureau. The history of Southwestern Colorado is designed to provide a baseline narrative for Cultural Resource Management. Paul M. O'Rourke has written a new history of the southwest corner of Colorado and in doing so, has provided a timely and original view of Colorado's heritage and history. This study will become part of the over-all history of Colorado as prepared by the Bureau and as other volumes dealing with Colorado history are written, they too will be made available to the general public. -
About Limes by George Geary CCP
All About Limes By George Geary CCP Lime History In the eighteenth century, Scottish naval surgeon Sir James Lind learned by his observation of long-haul sailors that citrus fruits conquered the dreaded scurvy (lack of Vitamin C) which had divested the ranks of the British navy more than any enemy. Between 1795 and 1815, some 1.6 million gallons of lime Juice drastically reduced the mortality rate of seamen. Along with their daily ration of rum, British sailors were required to consume a daily ration of lime Juice; hence British seamen became known as limeys. Since Britain was often at war with Mediterranean countries that exported lemons, limes imported cheaply from the English colony of Jamaica were substituted as the citrus of choice. Key Lime (also known as Mexican Lime and West Indies Lime) Cultivated for thousands of years in the Indo-Malayan region, this variety has long been treasured for its fruit and decorative foliage. The Key lime made its way to North Africa and the Near East via Arabian traders, and then carried on to Palestine and Mediterranean Europe by the Crusaders. Columbus is credited with bringing the Key lime to Haiti, where Spanish settlers to Florida carried it on. It flourished in South Florida, particularly the Florida Keys, hence the current common name of Key lime. Due to hurricane-depleted soils, locals switched from pineapple commercial crops to limes in 1906, and business boomed until a hurricane once again reared and wiped out the lime groves, never to be restored. Today, most Key limes come from Mexico. -
XXXX Gold $150,000 Golden Nugget 4Yo Championship
Wednesday 7 December 2005 XXXX Gold $150,000 Golden Nugget 4yo Championship History The Golden Nugget Championship began in February 1981 when the Victorian visitor Justin Hanover won for trainer/driver Tony Peacock. The WA Trotting Association had identified a gap in the national programme for a 4yo Championship and, similar to their innovation in running the first Australian Derby, set about attracting the best 4yos in the nation to Perth. To add to the uniqueness of the race the trophy always incorporated a Gold Nugget. The initial concept was for an elite field of eight heat winners only with four heats held on a Friday night and a further four heats on the following Tuesday before the Final on the Friday night. Over time that concept has changed due to a fall off in numbers of elite 4yos but that hasn’t stopped the Golden Nugget of continuing to showcase the nations best rising stars and the honour roll contains some of the greatest names seen in the past 25 years. Who will ever forget the awesome performance of Tasmanian owned Sinbad Bay in 1989 in setting a National 2500 metre record as he demolished the strongest Golden Nugget field ever assembled. The ten-horse field that year included six representatives from the Eastern States including the likes of Jodies Babe, Rowleyalla, Another Bart and the locally trained Manageable. The NSW sensation Westburn Grant overcame the infamous airline strike in late 1989 to show just why he was rated the best 4yo in the nation although he failed dismally in the WA Pacing Cup a month later. -
